> There is about a 1/2 second delay when using Orca with pulseaudio in Karmic.  This delay is unacceptable to the blind community, since it makes key echo useless, as you have to hit a key, and then wait for it to be read, and then hit another key.  In response, blind/visually impaired people generally try to remove pulseaudio from Karmic, with varying success.  However, those who have succeeded in reverting to alsa report much quicker Orca response.  There are no blind users who actually use Orca as installed by default in Karmic as their main system, so far as I know, because of this problem.
